This may be 1 of 3 things. 
#1- These images are a complete fake and someone is trying to stir up some rumors involving Rockstar and E32011. 
#2- These are "stolen" images from inside Rockstar that someone has posted to the internet.
#3- Rockstar is actually releasing these images to start the excitement for the highly anticipated fifth installment of GTA for E32011.
You be the judge...

Rockstar's new crime-drama action adventure title L.A. Noire has alot going for it. Massive story, long "career mode", interesting plot points and twists, interactive and character defining gameplay mechanics and techniques, and not to forget the facial-mapping and acting. L.A. Noire is so big that it takes up 3 DVD disc for the X360 and 1 full Blu-ray for PS3.

L.A. Noire will be 8sq.Miles of area for you to explore. From edge to edge it would take you 30minutes to traverse in a car. 




To put it in perspective here are a few game worlds you might be familiar with.
Mafia II - 4sq.Miles
GTAIV - 6sq.Miles
The Elder Scrolls III: Morrowind - 10sq.Miles
The Elder Scrolls IV: Oblivion - 16sq.Miles
Just Cause 2 - 385sq.Miles
FUEL - 5560sq.Miles
